Nicholson starts for Well; Clarkson in for Aberdeenpublished at 14:17 Greenwich Mean Time 16 March
Motherwell v Aberdeen (15:00)
Motherwell make just the one change to the side that started in their seismic win at Ibrox a fortnight ago.
The switch comes in midfield as Davor Zdravkovski drops to the bench for Sam Nicholson to make his first start at Fir Park.
It's also just the one change for Aberdeen after their poor defeat at Dundee in midweek.
It comes in midfield as well, with Killian Phillips out for Leighton Clarkson.
